[Heat illness in children].

A child's heatstroke is an unexpected accident; however, we are able to prevent it analyzing the situation which occurred, and its cause. The large-scale research about a child's heatstroke had not been carried out to the past in Japan. According to Heatstroke STUDY, more than 90% of a child's heatstroke were aged 6 and over; furthermore, 70% of those children were doing sports.

[Pediatric basic life support].

The new international consensus and guidelines were published by American Heart Association in October 2010. These guidelines include many important changes in pediatric basic life support(BLS) based on many evidences. Especially in children, asphyxial cardiac arrest has been more common than cardiac arrest and only one third to one half victims can receive bystander cardiopulmonary resuscitation(CPR).

Biobased polymer system: miniemulsion of poly(alkyl methacrylate-graft-lactic acid)s.

To broaden the application scope of lactic acid polymers, a new miniemulsion of poly(alkyl methacrylate-graft-lactic acid)s has been developed. The graft copolymer synthesis was based on a poly(lactic acid) macromonomer having a methacryloyl polymerizable group. The macromonomer and a comonomer of n-butyl methacrylate together with a suitable surfactant formed a miniemulsion of the comonomers in water.

Bone formation ability of carbonate apatite-collagen scaffolds with different carbonate contents.

Hydroxyapatite and carbonate apatites with different carbonate contents were synthesized, mixed with atelocollagen, and made into sponge scaffolds. The scaffolds were implanted into the bone sockets of the femurs of male New Zealand white rabbits for 2, 3, 12 and 24 weeks. carbonate apatite-collagen scaffold with 4.
